@MDM @terran thanks.
to summarize:
1) Contact our respective brokerages have them
recharacterize any 2019 Roth IRA Contributions as Traditional Contributions.
2) through brokerage
convert tIRA to rIRA (question below when)
3) Report the non-deductible tIRA contribution and conversion (executed by brokerage) on Form 8606.
Great. One detail, does step 2) need to take place after 2019 tax filings or before? after or before end of fiscal year 2019? In other words can I execute #1 and #2 in next 30 days, or do I need to wait?
