Live in Pennsylvania, work in DE but not permitted to go to DE office....tax refund?

Hello,

 

I am an IT worker who lives in Pennsylvania but my office of record is Delaware and I have DE states taxes (roughly 6%) taken out of my check.  PA state taxes are only 3%.  My question is, I was barred from entering my DE office starting around March 19 of 2020 due to the pandemic and I haven't been there since as it remains closed to me.  How can I use turbotax to file my taxes using an apportionment to get the DE state tax back that I shouldn't owe because I wasn't allowed to go to work there.  Thank you!
