Retirement tax questions

@dmertz 

The original taxpayer only mentioned “contribution“. They didn’t say what kind of contribution it was.  Most answers are assuming that the question refers to a traditional deductible IRA, but it could also refer to a Roth IRA or an HSA, both of which could also accept 2021 contributions up through April 18, 2022.   Just because this is the retirement section of the support forum doesn’t mean that every taxpayer will ask their question in the correct location.  I was covering all the bases.
