Deductions & credits

The original return was filed on 3/1/2024. I went through all the steps last night and today to amend the return and it only says to print and mail the state amended return. It says nothing for the federal except what you see. It doesn't even give me the option to file an amended federal return (only state) even though I went through all the steps.  The K-1 and Federal return 1120S say, "amended" if I look at my copies now, but TurboTax isn't prompting me to send anything to the IRS. That's why I'm here. What do I do? Just mail it? I just think that Turbo Tax should have prepared something for me to send as it did for the state.
