I entered 02/13/2024, and I just found the letter of confirmation from the IRS that states I am recognized with S-Corp status as of 2/13/24, so I just made all the dates in turbotax 2/13/24 and now it's fine... But even if I had not done that, my dates entered were prior to 3/15/24, technically I feel like it should have let me and still be retroactive according to the IRS instructions.
