IRS Exception: if you summarize Category A or Category D, Form 8949 is not needed for transactions without adjustments. No mailing is necessary.

As an active investor, be aware that your category Box A or Box D sales without adjustments do not require Form 8949, so there is no reason to import or key in those transactions.
Instead use the "enter a summary" option to put your numbers on Schedule D Line 1a or Line 8a.
--
If you have wash sales, it gets more complicated since those adjusted transactions have to be itemized on Form 8949 and the summary totals adjusted accordingly.

In your situation, that exception is not going to help much.
Again, I advise going with the other tax software that will let you attach your 1099-B PDF when you e-File.
You can even separate it into multiple PDF files if one PDF is too huge.
