I'm not seeing an easy way to do that in TurboTax (TT). You may have to contact TT support (I suspect they may not be able to help you)

I have taken a look at it and this is how I would do it (I have download TT, not online).
At the screen "Your 2022 Ohio Taxes are ready for us to check"
-Click Other situations
-Scroll down to School District taxes.
-Click Edit
-Go through the interview and change everything thing to what it should be.
-Click on "forms".
- Open SD100
- Review the SD100 for accuracy
- Check the AMENDED RETURN box at the top left of SD100 -that will cause form SD RE to be generated, by TT, and added to the forms list
- Fill out the SD RE form manually
- Print, Sign and Mail the two forms (SD100 & SD RE)
I'm not sure the forms can be accessed in online TT. If not, print out the SD 100, check the AMENDED RETURN box manually. Get the SD RE form here: (https://tax.ohio.gov/static/forms/ohio_individual/individual/2022/sdre.pdf) and fill it out manually
This was not something that TT is able to "catch". You are asked, in the SDIT interview about your SD residency status. Included is a box asking if tax was mistakenly withheld for the wrong district. You must answer those questions correctly to get the right result. Note: you will not get the mistaken withholding question when you go back and edit, but you can select "I did not live in Scholl district number #### at any time during the year".
