If you lived in Florida for the entire year, you don't own Virginia any state taxes for your retirement income in that same year.
If you had Virginia state withholding on your retirement income for a year when you didn't live in Virginia, you can file a Virginia nonresident tax return to get a refund of that tax withheld.
All your retirement income is taxed at a federal level, so you will need to enter all 1099-R forms you received for a given year.
