Do I need to file a state tax return?

[rayandpam04]

I moved from Pennsylvania to Florida in October 2017.  I filed my 2017 taxes as a resident of Florida.  I just realized that my employer withheld a significant amount of Pennsylvania tax income in 2018.  Do I have to file a Pennsylvania Non-Resident state tax for to get that money back?

We did still own a home in Pennsylvania that we sold in July 2018.
