why does my form SD 100 for local school district income tax ask for a residency end date if i still currently live at the same address?

This question is only asked if you are a partial-year resident.  If that is the case, make sure you enter the date as  two-digit month and two-digit day.  Enter the date that you first moved in to Ohio and enter 12/31 for the end date.  If you are a full-year resident, it shouldn't ask for these dates.  

If you continue having issues with the return, you can try to delete your state and start it again.  You might also need to clear your cache (that is, remove these temporary files) because a full or corrupted cache can cause problems in TurboTax.  You can try these steps if you are using the online version:

• Clearing your Cache and Cookies
• Using a different browser
• Opening an Incognito Window

Please reach out again if your problem persists.
