"Wondering how to proceed since tax season is coming up."

This is the peer user community for using the ProSeries tax preparation program to prepare clients' income tax returns. That program will have the provisions for the entries for the tax payer unit. You proceed as usual.

The IRS is the best resource for the general public.

You seem to be lost on the internet. I have bookmakrs for stimulus info; it can be found at these links:
