@gerda0427 - since the difference is $2800, it is surely Line 30.
Line 30 is supposed to be
a) the number of people listed on your 2021 tax return TIMES $1400
b) less what you already received, but not less than zero.
the biggest confusion I see is that if you filed "joint" and entered what was on Letter 6475 into TT, there were actually TWO letters (one addressed to each spouse) and the amounts on the two letters were to be added together and entered into TT.
check you bank account statements from March - May, 2021 to reconfirm what you ACTUALLY received and see if my math doesn't explain why the IRS reduced the refund by $2800.
does that help?
