Neither the IRS nor the tax code uses the term "unqualified contributions" with respect to IRAs. I'm trying to determine if your contribution was an excess contribution or not (because you did not have earnings to support the contribution or you were over age 70½), or if it was not an excess contribution but was simply not a deductible contribution. Your original question and subsequent responses are somewhat contradictory in this respect. Your mention of being covered by a 401(k) plan suggests that the contribution made for 2016 was simply a nondeductible contribution, not an excess contribution, and there was no requirement to take the money out of the IRA.
Did you use TurboTax to prepare your 2016 tax return?
As part of your dealings with the IRS, did you file a 2016 Form 8606?
Did the IRS tell you that you must take the money out of the IRA?
Did you have a nonzero balance in any traditional IRAs at the end of 2019? (A 401(k) is not an IRA so don't include that.)
