dependent covered under parents HSA HDHP what do I enter in turbotax

[maple1202]

my dependent is trying to complete his return and keeps getting errors.  He is covered under my family HSA + HDHP and does not have any other plans. if he doesn't say he had an HSA then it says he had a lapse in coverage.  if he does say he had one with no contributions or expenses it complains he should not have checked family on 8889-T worksheet for each month in line 3 or that he should not have selected self-only on those lines depending on whether he selected family or not in easy-step. 

what is is supposed to enter?

A dependent is not eligible to contribute to an HSA. 

He should not have indicated that he had an HSA. BTW, there is no such thing as a "family HSA". Each HSA is owned by an individual, i.e., you or your spouse.

"if he doesn't say he had an HSA then it says he had a lapse in coverage. " This comes from the question, "What type of High Deductible Health Plan did [name] have on December 1, 2020?"

Your dependent should answer this one as NONE.
