Deductions & credits

Im not being claimed as a dependent and the 2020 stimulus is based on 2019 income. I qualify based on 2019 income. What my wife and I receive this year should have no affect on the stimulus paid this year. If I am incorrect please point me in the direction of that information because nothing I've read mentions anything about 2020 income. Also, since I receive the 2nd payment I should have received the first since they were both based on the same tax year.
