Investors & landlords

Kathryn, thanks for your answer. I have around 100 transactions. I noticed that TurboTax reported some of them in form 8949 and the summary in Schedule D line 1b. However,  some of the transactions were not reported in form 8949. For these transactions, the summary was reported in Schedule D line 1a. I could not figure out why some transactions are reported in 8949 and not others. All the transactions are similar in nature. Would you know why TT might be splitting the transactions between lines 1a and 1b in Schedule D?
