As you enter your info and forms like W2 and 1099R you are filling out the 1040 or 1049-SR. You automatically get the 1040SR if you or your spouse is 65 or older. And Turbo Tax automatically gives you the Standard Deduction unless your itemized deductions are more.
The 1040SR is EXACTLY the same as the regular 1040 just bigger type so it prints on 3 pages instead of 2. And the Standard Deduction is on page 4. They both use the same instructions and tax calculations.
