I have two 8949 forms. The second form has box F checked. More properly, box E should be checked. If I override box E, the transaction from my first 8949 form over writes the transaction on the second form and the information on the second form is lost. How do I get box E checked and retain data on the second 8949 form? Information on the second form comes from Schedule K-1 complete disposition of activity.
Do not use override. It causes problems (as you found out).
if your information is from a K-1, then it is not from a 1099-B, and Box F is the correct box.
Sale was reported on 1099-B from Fidelity showing sale and long term realized gain. Top of Form 1099 B states "report on Form 8949 with Box E checked and/or schedule D, Part II." I stand by statement that Box E should be checked on Form 8949, not Box F. If I override and check Box E, detail on 2nd Form 8949 is overwritten by detail from unrelated 1st Form 8949 (a bug, I suspect). I left Box F checked and was able to manually enter gain on Schedule D next to line stating "Box E checked" so increased tax is computed properly. Kindly, Neal
