Everyone files on the full 1040 now. The 1040 SR is exactly the same but with larger type so it prints on 3 pages instead of 2. In the Online version you automatically get the 1049SR if you or your spouse is 65+. In the Desktop program you can pick and force the one you want.
Did you itemize last year for 2020? If you took the Standard Deduction you don't need to enter your state refund. A State Tax Refund is taxable if you itemized deductions on that prior year's federal return and took a deduction for state income taxes instead of the sale tax. You got a deduction benefit for it so now you have to include it as income. If you took the standard deduction it is not taxable and you don't need to report it.
