If you simply want to fill in forms then get them from the IRS/state  and mail in the returns.

The IRS and most states have online forms that you fill in the blanks and then e-file for free.  There's no need to mail your returns.  On the other hand, there's no need to use commercial software if the only function you need the software to perform is to check your math and then e-file.
