" I have been making traditional IRA contributions and recharacterizing (in the same year) to Roth the last few years. "
This is exactly as I surmised in my original reply above.
Recharacterization is not a backdoor Roth contribution and will generate a penalty for excess contribution when contribution is disallowed.
@manwithnoplan
However , Code 2 is not a recharacterization ; you are not entering correctly into TurboTax.
