AMENDING 2020 1040 FOR RECOVERY REBATE ERROR - Intuit Accountants Community

Here you go... be sure and read my last post.  guidance says we do have to amend IF you didn't claim any RRC on the original return.

if you entered wrong amount:

 DO NOT file an amended tax return with the IRS. If you entered an amount on line 30 but made a mistake in calculating the amount, the IRS will calculate the correct amount of the Recovery Rebate Credit, make the correction to your tax return and continue processing your return. If a correction is needed, there may be a slight delay in processing your return and the IRS will send you a notice explaining any change made.
