In 2022 I made a nondeductible contribution to a rollover IRA. In 2023, I rolled over the whole rollover IRA into a 401k, zeroing it out the rollover IRA. I then did a backdoor Roth by contributing to a new traditional IRA and converting it to Roth. I now realize that my tax returns are showing I still have a basis in traditional IRA even though all my traditional IRA accounts are $0.
How do I fix this?
