After you file

Hello @DianeW777 

I'm sorry but I'm confused. The publication clearly says that if I didn't ask for the RRR on line 30 of my original 1040 that the IRS will NOT calculate a RRR for me unless I file an amended return.  Can you please help me understand why Turbo Tax team is telling me not to file an amended return but IRS says I must file amended return to claim the RRR? Thank you!

A1. If you didn't claim the credit on your original tax return, you will need to file an Amended U.S. Individual Income Tax Return, Form 1040-X. The IRS will not calculate the 2020 Recovery Rebate Credit for you if you did not enter any amount on your original tax return.
