@djeffbland You are adding on to a post that is several years old. What are your details? Where is it showing as income?
If you are looking at a summary screen or review screen those show the full amount as income and lump a lot of stuff together. You need to check the actual 1040 form and make sure it's right.
If you rolled it over it should say Rollover to the left of the taxable amount on 4b or 5b.
