My understanting is that if your AGI does not exceed $75,000 for 2018, 2019, or 2020, you are entitled to a rebate credit of $1,200 (paid last year) and $600 (paid this year).  I'm saying that my taxpayer is entitled to a rebate credit of $1,800 because her 2018 AGI did not exceed $75,000. I know that many taxpayers did not receive the rebate credit if their AGI exceeded the max in any of the years.  Be that as it may, they are entitled to receive the credit if their AGI qualifies in any one of the 3 years.  As far as I can see, ProConnect's input fields do not permit entering this information.
