Get your taxes done using TurboTax

I was trying to help my college age son with what should be really easy taxes.  We used TurboTax last year without issue.  This year, it wouldn't accept the 2019 AGI value for e-filing purposes.  I found that very strange since the application pulled the data directly from last year's data file.  How could it be wrong?  I then attempted to complete the information stated at the link shared, specifically to obtain an online transcript of his 2019 tax filing.  We got to the part about entering the last 8 digits of a credit card and the IRS site would not accept it.  

 

Something is seriously wrong here.  Any guidance?
