I paid a sewer tax. where do I enter that.

You can not deduct sewer taxes.

This, from IRS Publication 503, Deductible Taxes:

Some taxes and fees you can't deduct on Schedule A include federal income taxes, social security taxes, transfer taxes (or stamp taxes) on the sale of property, homeowner's association fees, estate and inheritance taxes, and service charges for water, sewer, or trash collection.

As a renter is this ever possible?

@clarion6255 You are posting to a thread that has had no activity since 2019.   No, if you are a renter you cannot deduct anything for sewer tax.   In fact, there is no place to enter anything about rent on a federal tax return.   If your state has any sort of credit for renters it will appear on your state tax forms.

As far as I know, the states that have anything for rent are Arizona, California, Connecticut, Hawaii, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Jersey, New York, Rhode Island, Vermont, Washington DC, and Wisconsin.
