My employer 401k plan allows for pre tax and Roth contributions as well. The pre tax and roth contribution combined limits are $19000. I DO NOT directly make any Roth contributions. I however, make post tax contributions to 401k (combined limits for all contributions are 50k) and then do the "in plan conversion" to Roth. I receive 1099-R for this conversion. Is this 1099-R reporting a rollover of funds from 401k plan to a "Designated Roth 401k" plan?
Yes, your 1099-R may report a Rollover from your 401K to a Roth 401K.
Enter your 1099-R as shown, and pay attention to the follow-up questions asked in TurboTax.
If you received a pre-tax deduction for your 401K Contribution, you will be taxed on the amount you rolled into the Roth 401K.
