Be aware that in some states it can take several weeks to process an amended return, especially if they review it manually.
If due a refund, see if it shows up in Pennsylvania's refund lookup tool. I don't know if an amended return will show up there or not.

Or phone the PA DOR to inquire about its status and how to check on it in the future. The phone number for "Personal Income Tax" is shown in the table at:
