Simple answer: yes.
But, it's not clear which credit (American Opportunity Credit [AOC] or Lifetime Learning credit [LLC]) you got.
There is a 4 time limit to claiming the AOC (the much more generous of the two). Since this is his fifth calendar year, you may not be eligible. You have to tell TurboTax how many times you (and your son) claimed it in the past. There is no limit on how may times the LLC can be claimed.
You say your son has been going to school part time. That brings up the question as to whether you are able to claim him as a dependent.
There are two types of dependents, "Qualifying Children"(QC) and standard ("Qualifying Relative" in IRS parlance even though they don't have to actually be related). There is no income limit for a QC but there is an age limit, Full time student status, a relationship test and residence test. Only a QC qualifies a taxpayer for the Earned Income Credit. They are interrelated but the rules are different for each.
The support test is different for each type. The support test, for a QC, is only that the child didn't provide more than half his own support. The support test for a Qualifying Relative is that the taxpayer provided more than half the relative's support.
A person can still be a Qualifying relative dependent, if not a Qualifying Child, if he meets the 6 tests for claiming a dependent:
- Closely Related OR live with the taxpayer ALL year
- His/her gross taxable income for the year must be less than $4300 (2020).
- The taxpayer must have provided more than 1/2 his support
In either case:
- He must be a US citizen or resident of the US, Canada or Mexico
- He must not file a joint return with his spouse or be claiming a dependent of his own
- He must not be the qualifying child of another taxpayer
