Two years of efilings rejected for not having “signature PINs” matching the previous year. Missed efiling last year because Turbo Tax never sent promised text msgs.

Also, supposedly a couple of years ago PINs were made optional if previous year's AGI is entered.  Both times I had that in disputably correct.  IRS couldn't tell reason, suggested setting AGI to 0 or 1 becausef iling was late last year because TT never send text messages as promised:  email is insufficient.) Couldn't figure out how to do that -- it's not in the forms nor the topic list.
Gave up and mailed.  Sick of TT's declining quality.
