@rgcaryjr You each should have got a letter for half 2100. The IRS is saying they sent you 4,200 which is the 3rd Stimulus for 3 people (1,400x3=4,200). You needed to report the full 4,200 on your tax return. Then line 30 would be 0 or blank. You tried to claim it again on line 30. Line 30 is only if you didn't get the full amount (but you did) or if you qualify for more.
I think the IRS is having problems sending out the spouse's 6475 letter. But you needed to enter the full amount you did get which was the 4,200.
