I opened a solo401k, does TurboTax provide the forms for a tax credit?

[tagteam]

TurboTax has Form 8881, if that's what you mean.

I'm not sure that's the proper form, though, so I'll page @dmertz.

Did you find where to enter the solo 401K ?  Where to enter Self Employed solo 401K plans

You can contribute to a 401K up to the amount of your Net Profit reduced by 1/2 of the SE tax OR to the max contribution allowed for a 401k whichever is Less.

You might qualify for the Savers Credit

I don’t know where it is.  It might be under

To qualify for the credit for pension (401(k)) startup costs, the company has must have at least one employee who is not a >5% owner.  Since a solo 401(k) likely implies that there are no such employees, it seems likely that this credit would not be permitted.  For a sole proprietorship, you can enter the pension startup cost into TurboTax as a business expense, answer TurboTax's related questions, complete the corresponding section under Business Deductions and Credits and, if you qualify, TurboTax will prepare Form 8881.
