Alright guys, you ready for this? My 1,000th post!!! You know, I'd like to thank my Parents, my Family, my Friends, the little people, and of course, this forum. This is a truly special day!
Sorry Cathy, I'm not hijacking here. I had the exact same issue/letter for my client, for tax year 2017, and I also use Drake. I filled out the 2119 (Home Sale Worksheet). I assumed this form transmitted, my client was able to exclude the full gain, but alas, he gets the nasty CP2501. I responded to the IRS with the same Worksheet 2119 (HOME in Drake), as well as a Schedule D, reporting the full gain. Then, in the middle of the D Screen, there are 3 Adjustments with pull down tabs; I selected "H", then I put a negative amount (same amount as the gain) in the box next to the H (adjustment to gain or loss), which zeroes out the gain. The worksheet explains the cost basis (improvements, etc), and the Schedule D reflects the holding period.
That, and a letter indicating the taxpayers wish to elect to exclude the gain, or as much gain as she can, and also I would mention the sale was reported, but on the Worksheet, which you assumed was attached to the return, or some other type of feel good language, etc.
Good luck, I will let you know if I catch any flack from the IRS on the response.
Again, thank you all, 1,000, I really didn't think I would live that long!
