My property tax statement says RES HOMESTEAD under the property classification line, but TurboTax requires a code like 1a, 2b, etc.
1a. is Residential Homestead
Please use that code.

Update
I found online where the classification is 1a/1b/4bb RESIDENTIAL SINGLE UNIT, but each of those codes are separate on TurboTax.
