Make sure you do it right. If you are rolling over $100,000 (for example), you might be subject to mandatory withholding of 20% so you would get a check for $80,000. But you must deposit the entire amount ($100,000) in the new account, making up the difference from your other funds. Then you will get the withholding back when you file. IF you only deposited the $80,000, the other $20,000 is deemed a distribution and will be taxed as income plus a 10% penalty.
If you did a direct transfer from custodian to custodian this would not be a problem.
You will get a 1099-R form showing the distribution. You will enter it in Turbotax and answer some questions to confirm this was a rollover. No tax will be owed as long as you do it right.
If you have no other income in box 7, you may be blocked from e-filing, so print your tax return and mail it in.
