it is correct ; there is no bug - here is the math:
You are eligible for the GREATER of what you received in stimulus payments or what the 2020 tax return calculates. That is why the payments are called 'stimulus' but on the tax return it's called 'recovery credit'
you state you received $2244.50 and $1144.50, it does not matter how they were calculated using either your 2019 or 2018 tax return, but that is the cash you received. In total $3389.00
Based on your 2020 tax return, you are eligible for 2 taxpayers and 2 children. Since your income is $176,508, each of the two payments is reduced by 5% * 26, 508 or $1325.40. The credits are reduced if your 2020 income is over $150,000
for EIP1, you get $1200 + $1200 + $500 + 500 - $1325.40 or $2074.60
for EIP2, you get $600 *4 or $2400 - $1325.40 or $1074.60
that totals to $3149.20
Based on the information on your 2020 tax return, you are eligible for $3149.20 and you actually received $3399. Since the stimulus payments are greater than what is calculated based solely on your 2020 tax return, you are not eligible for more, so Line 30 is Zero.
You are also not required to return the excess; in other words Line 30 can never be negative.
does that make sense? the program is working correctly and your children were part of the calculation.
