If you recieved part of your spouse's 401(k) pursuant to a QDRO, you have 3 options.
1. Roll the money over into your own retirement account (and pay tax when you withdraw the money in retirement).
2. Take a lump sum distribution and pay regular income tax but not the 10% penalty for early withdrawal.
3. Take annuitized distributions over your expected life time and pay regular income tax but not the 10% penalty.
You should have received a 1099-R from your spouse's retirement plan, enter it in Turbotax exactly as you received it.
