In early 2024 I accidentally rolled Roth 401k monies into a new IRA that I thought was set up as a Roth (at the same time, I rolled regular 401k monies into an existing traditional rollover IRA, so I had no reason to set up a new traditional IRA, only a Roth).
I discovered the error while preparing my 2024 tax return in January, filed a return of excess contribution and then deposited the monies I received into a new Roth IRA.
My question now is how this is addressed on my 2024 tax return, if it is addressed at all. I figure I will worry about how it is addressed on the 2025 return next year!
