if you could not be claimed by your father in 2020, you should have received the recovery credit on Line 30 of Form 1040 which in effect is the first two stimulus payments. There should be $1800 on Line 30.
Then depending on when you filed your 2020 return and when the IRS created the $1400 payments , you are either going to get the $1400 in the next few weeks OR you will have a 'recovery credit' of $1400 on your 2021 tax return.
if your CAN'T be claimed by your father in 2020, his income has nothing to do with the situation for any of the 3 stimulus payments.
