First, did your dependent ever take the Hope Credit?
Second, when you say, "TurboTax prefilled 3 on form correctly", where are you referring to? In the TurboTax interview where it asks, "Enter the number of prior years that the American Opportunity Credit and Hope Credit have been claimed for [name]"? Or somewhere else?
Third, when you answered "Yes" to "Yes, [name] received one or both of these credits in a prior year", did several more lines appear below, and what were the values in the boxes below (if any)?
Hi - 1) no. 2) Yes, the number was prefilled in the interview section. 3) I answered yes in the interview, but I did not see several more lines below breaking out my dependents. This is the third year my dependent was eligible, and the third year I'm using TurboTax, so I expect the system to know what was submitted the previous years and account for it. I appreciate the help.
Form 8863 line 23 asks “Has the Hope Scholarship Credit or American opportunity credit been claimed for this student for any 4 tax years before 2020? “
You say it was claimed THREE years, not FOUR, so the question is properly answered "NO".
If you claim the American Opportunity Tax Credit on your 2020 return, that credit will no longer be available for that student going forward.
