How do you re-set your "thunderbird account" ? I am having trouble sending emails.

Not sure what you mean by "reset" in the context of email, client or otherwise. You can always change the settings in any client for the associated account. For att/yahoo email the proper server settings are defined here. That article also recommends you use a secure mail key instead of your account password.
You say you have trouble sending. What happens when you send? Can you even send in the webmail? If not change your account password (e.g., Forgot ID/Password).

ATT just had a security update that they did not notify anyone about, not even their support people. See
you need to create a secure key but that may not resolve your problem. since they have a bug.
Your reply to address must be the same as your ATT address
The error message says something about no mailbox
The secure mail key has been around since about February 2018 so it's not new. But that's the way att "announces" changes. It's stupid, I agree. Like you just have to know it is there. But that's the way it is. Since that time they have added the secure key reference to other articles (the email client setups and the server settings) so it' not as secret any more.
As for the reply-to email address being different from the actual account there was just another recent thread on that problem. That's a separate problem from using the secure mail key. As I posted in that thread I have no explanation why that is happening. If the reply-to is accepted as valid in the webmail settings (which makes one wonder why you have to do it there if you are using an email client app instead of the webmail) then I believe it should work. It does for me and by the way I also use Thunderbird. I think validating the webmail reply-to setting is something more recent because I think you used to be able to put any email address in there. I guess it's to discourage using att/yahoo accounts for spamming.
FWIW I use a forwarding service too but then my reply-to was set in the webmail many years ago.
As for the error message IMO that's business as usual with yahoo. It must be beyond their capability to just say reply-to (of From) email address invalid or something more to the point.
I am not sure this was changed way back when the secure key was added because yours and the other thread (and possibly yet another thread I just saw - they haven't answered my reply yet whether they are using a different reply-to but there description sounded like it was) haven't reported problems like this before a day ago in these forums as best as I can remember.
