The IRS does not require all transactions to be reported on Form 8949 Sales and Other Dispositions of Capital Assets. For transactions with reporting category "A" or "D" (meaning the cost basis was reported to the IRS), if there is no adjustment code/amount, they can be reported directly on Schedule D (Form 1040) Capital Gains and Losses, Lines 1a and 8a, respectively. If you would like all of your transactions to be listed on Form 8949, you can force the program to print Form 8949. They will then be reported on Schedule D, Lines 1b and 8b.
To force all transactions to be listed on Form 8949:
The TaxAct program will only print both pages of Form 8949 if you have entered both short-term and long-term transactions.
Per IRS Instructions for Form 8949, on page 3:
You don't need to complete and file an entire copy of Form 8949 (Parts I and II) if you can check a single box to describe all your transactions. In that case, complete and file either Part I or II and check the box that describes the transactions.
Otherwise, complete a separate Part I or II for each category of your transactions, as described above.
