My wife quit her job/1099R

What's in box 2a of your 1099? Should be 0 if it's non taxable. You will still receive a 1099 even though none of it is taxable.

The distribution from the 401(k) should have been subject to at least 20% withholding unless it was a direct rollover. If it was a direct rollover, then Box 7 of your Form 1099-R should have a Distribution Code G. Your tax return software should ask you to input the type of distribution you received as indicated in Box 7. If there is a code other than G in Box 7, then reporting a rollover is a bit more complicate. However, the software should still give you the opportunity to disclose that an indirect rollover occurred.
