Don't know who you talked to but that is a bunch of crap ... however if you did not get the ADVANCE of the credit in 2020 then you can apply for it on the 2020 return when you file next year if you are eligible to do so. The IRS has line 30 on the form 1040 and a worksheet for this already in place. In the TT program it will ask if you got it and how much ... that is all you will need to do for the program to do the calculations. See pages 56-57 ... https://www.irs.gov/pub/irs-dft/i1040gi--dft.pdf
