"If you e-file your return but choose not to report each transaction on a separate row on the electronic return, you must attach Form 8949 to Form 8453 (or the appropriate form in the Form 8453 series) and mail the forms to the IRS."
IRS - Instructions for Form 8949 (2024)
"Use Form 8453 to send any required paper forms or supporting documentation listed next to the checkboxes on Form 8453."
Form 8453 - U.S. Individual Income Tax Transmittal for an IRS e-file Return
Since you DID list each transaction separately, you do NOT need to mail in Form 8949 nor Form 8453.
