Cannot enter foreign (Canadian) zip code in zip code field. Canadian zip codes have letters + numbers; only numbers are accepted. Also is making me choose a state.

To enter a Canadian postal code in TurboTax, you must select the Foreign or US territory option for the address type. This changes the input fields to allow for Canadian provinces and postal codes.

I'll assume you are preparing a USA tax return, since you are in the USA TurboTax forum.  If you are needing to prepare a Canadian return, you are in the wrong place.   Canada TurboTax is a different site and different online program.

So assuming you are preparing a USA return, whenever there are address fields, one of the first fields asks you to choose the "type" of address.   When you choose "foreign or US territory", then the boxes will reformat, and you will see a place to enter your country and the international postal code, including letters.

If Canada was your resident "state" for 2025, then on a different screen where it asks what state you lived in on December 31, 2025; i.e., your resident state, in the dropdown menu when you scroll way down past Wyoming you will see "Foreign or US territory".
