After you file

Do loop of information. Rejected -->Confirm AGI --> Confirmed with number from Turbo Tax AGI from 2018 --> e-file again --> Rejected.... and on and on. I did not find an alternative to fixing this problem or what to do if not resolved. ALso, with the rejection, Turbo Tax highlights the PIN number. Am I to remove? Nothing to change. I am making an assumption that my ONLY option is to file by mail. Now, it is not clear if I need a letter or include the rejected notice with the mailed copy to show I filed on time. Frustrating and makes Turbo Tax more trouble than the help it provides. There are options to Turbo Tax and after 5 years of purchasing, I will not again.
