Claire:
I totally agree with you. This is for my 2022 return, which I will file electronically. I printed out form 8453 from the IRS and it specifically states to "file this form only if you are attaching one or more of the following forms or supporting documents". The last box deals with form 8949. However, it says to only check this box if you elected NOT to file 8949 electronically. However, my return had a copy of 8949 filed electronically. Therefore, I doubt one would need form 8453, and one might need to just mail the generic Section 751 letter to the IRS outlining the date of sale, amount in column 7, and the capital gain/loss for each sale (contained in the sales schedule one would get from the PTP after the sale)
