I rent in Florida so house in WV is still first home. No capital gains. Did file WV extension
When, exactly, did you become a Florida resident? Was it in the 2021 tax year? If so, should you not be filing a part-year WV return?
If you moved out of WV during 2021, then you are a part-year resident of WV and a part-year resident of FL. You owe a WV tax return for the income you earned while living in WV, and you owe income tax on the sale of this home because it was located in WV.
If you moved out of WV before 2021, then you are a non-resident of WV. You only owe income tax on WV-source income -- that would be job or freelance income you earned if you did the work in WV (such as a working vacation). The sale of the home is also considered WV-source income.
What should happen in Turbotax is that you list all your income on your federal return, including the sale of the home. Then, all your income flows to the state return, and Turbotax will ask you to allocate your income by source.
Did you list the sale on your federal return? If not, go back and do that. Also note that WV is a "conforming state" with regard to capital gains. If the sale of your home is not taxable on your federal return because you meet the 2 year/5 year rule for your main home, it is also not taxable on your WV return. But if you had mandatory tax withholding, you have to file to get that refunded.
If you still need help, you may need to call support and speak to a WV specialist, since the different state tax programs are different.
