Can i speak with someone on phone/live from TurboTax? I just e-filed my return & IRS rejected it! (?) I'm positive I entered the correct AGI from 2021 Tax Return!

If the 2021 tax return was filed late 2022 or early 2023 there is a good possibility that the IRS does not have your 2021 AGI in their database.

Enter a 0 (zero) for the 2021 AGI and e-file the 2022 tax return again.

Try going to IRS.gov website. Make an account if you don't have one already.  You can look at the record of your previous tax return which will include the AGI.
