This last calendar year (2018) I opened up a traditional IRA and contributed $5500. However I did not do all my homework and discovered, after the fact, that money is only tax deductible if I don't participate in a employer sponsored retirement program (I currently max out my contribution to a 401k).
Overall this doesn't bother me, but since I've paid taxes on the $5500 already I'd like to put it into a Roth IRA and not incur any further tax penalties. Is there any way to recover this money without having to pay taxes twice?
