Error due to Form 3800

When I filed my Return (2024), it was rejected because of error due to 3800, page 9

Two doubts:

1. I did not have any business income in 2024.In earlier years, I used to get a K1 from an S corporation. The investments were sold in 2023 and duly accounted  (loss). Why does TurboTax (TT) create a Form 3800 this year

2. The error message (when I tried to file the Return this year), also said to wait till March 27. Any particular reason? Is the software being rectified?

3. If I merely delete the Form 3800, will it create any error.

 

Thanks in advance
