Forgot to file schedule D

Hello,

 

I filed my taxes for the 2021 calendar year, but I forgot to file a schedule D since I sold stocks from my companies stock options and RSUs. The capital gains from these stock options and RSUs were all included in my company's W-2 and were all short-term capital gains, so I paid the correct amount of taxes, I just forgot to report the schedule D.

 

I'm trying to figure out how to let the IRS know that I forgot to send in a schedule D but from searching online I can't find anything. I e-filed with TurboTax and I'm trying to use their flow to amend my tax return but there's no option to send in an amended schedule D.

 

Also curious of how bad of a spot I'm in? Any help here would be appreciated, thank you!

 

Related: I did the same thing (forgot to send in a schedule D) for 2020 but I only realized I had made this mistake after I had already filed my 2021 taxes. So for 2020, I got a CP2501 form from the IRS, which basically just said "Hey your brokerage said you actually netted this much from your stock sales, is this correct?" and I replied "Yes, and here's a filled out schedule D and Form 8949 that I should have filed with you all for the 2020 tax season". Hopefully that closes the loop with the IRS on the 2020 calendar tax year.
