If it was a loan on your 401k, you don't have to include it. If you took a distribution on your 401k, you'll be receiving a 1099-R that you'll enter into TurboTax. The fact that it was a deposit to buy a home is irrelevant for tax purposes.
Note: 401k distributions to for the purchase of a home are subject to 10% penalty if it's a premature distribution before age 59-1/2
You'll get a 1099-R if you received $10 or more from a retirement plan. Here's how to enter your 1099-R in TurboTax:
1. Open (continue) return if you don't already have it open.
2. Inside TurboTax, search for 1099-R or 1099R (lower-case works too) and then click or tap the "Jump to" link in the search results.
3. Answer Yes on the Your 1099-R screen, then click or tap Continue.
· If you land on the Your 1099-R Entries screen instead, click or tap Add Another 1099-R.
4. Select how you want to enter your 1099-R (import or type it in yourself) and then follow the onscreen instructions.
