Get your taxes done using TurboTax

My federal efile has bounced twice.  Both times, the reason given was AGI or PIN wrong.  AGI is correct.  Turbotax filled it in from its record of my 2019 return and I checked my own copy.  PIN does not match last year because I did not use efile in 2019.  There was no PIN last year.  Apparently, I am not allowed to use efile because I did not use it last year.  That is absurd.  Is it the fault of Turbotax or the IRS?
