Can I get a refund if I can’t go back to the hotel I booked for quarantine in Shanghai?

Yes.

The hotel can issue refunds during the epidemic. Affected by the epidemic, if you don't check into the hotel you booked in advance, you can ask the hotel to refund all the room payment, but the prerequisite is that the epidemic must be serious.

During the epidemic period, including hotels and air tickets booked, as long as the country has regulations, then as a merchant, you must refund them in accordance with the law. You cannot refuse to pay in violation of the law, so you must be sure when handling them. The process must be followed to ensure that the interests of the parties involved will not suffer any losses.
