Form 1040 Line 4a

[Curious George]

Quick question about line 4a on Form 1040:

Should this line be $0 or $12000 after having done a his and hers back door Roth IRA?

Line 4b is definitely $0 as instructed on the bottom of Form 8606, but I’m not sure is line 4a (IRA distributions) should list the gross distribution from line 1 on Form 1099-R.

Thank you.

Mine in 2021 shows 12,000 on 4a, and nothing in 4b.

Got it. Thanks!

Agreed. I usually have more than $12K there due to Mega Backdoor Roth IRAs.
