Retirement tax questions

Yes as long as the money comes from "taxable compensation".

 

(Taxable compensation is generally wages that you worked for - W-2 or net self-employed income minus the deductible part of the SE tax, but can include commissions, certain alimony and separate maintenance, and nontaxable combat pay ).

 

See IRS Pub 590A "What is compensation" for details:
