After tax Roth 401k contribution
I have a solo 401k. For the 2022 tax year, I plan on making the maximum employee contribution and make up as well as the maximum employer contribution. I want to make an additional after-tax Roth 401k contribution up to the 2022 limit of $67,500. Can some tell me where I report this additional after-tax Roth 401k contribution in TurboTax?
