When I check the "maximize contribution" box, Turbotax says I can defer a maximum of $24924. I believe this includes some amount of catch up contribution. This corresponds to line 14 on TT's "Keogh, SEP and SIMPLE Contribution Worksheet".
However, line 21 of TT's "Keogh, SEP and SIMPLE Contribution Worksheet" says the maximum deductible contribution for MP, PS, SEP & Individual 401k plans is a greater amount, namely, $30,849.
When I tweak the numbers on the retirement contribution screen, I can see that my refund maximizes right at $19,000 deferral with a $3,000 catch up contribution, so there doesn't seem to be any point to contributing the full $30,849.
If I truly have a cap of $30,849, and I only make a $19,000 deferral and $3,000 catch up contribution to the pre-tax 401k, do I still have a remaining $8849 that I could contribute to a Roth 401k?
