Tennessee has no tax for 1040. They used to have a hall tax and that went away https://www.tn.gov/revenue/taxes/hall-income-tax.html#:~:text=It%20was%20enacted%20in%201929,1%2C%20....

Use US as the resident state on the 1040

I believe the TN form for the 1120S is the FAE 170 and you should be able to read through the instructions https://www.tn.gov/content/dam/tn/revenue/documents/forms/fae/fae170instructions0819.pdf
