Unfortunately the 3,000 record limit cannot currently be changed.

However, you can quickly enter this manually.  Your brokerage statements should include a summary of your transactions, grouped by sales category.

There are seven possible "Box" designations that indicate the holding period (Long/Short Term) and the reporting status.  These are the only ones you have to summarize.

Code A. This code indicates a short-term transaction for which the cost or other basis is being reported to the IRS. Use this code to report a transaction that the recipient will report on Schedule D (Form 1040), line 1a, or on Form 8949 with box A checked with totals being carried to Schedule D (Form 1040), line 1b.

Code B. This code indicates a short-term transaction for which the cost or other basis is not being reported to the IRS. Use this code to report a transaction that the recipient will report on Form 8949 with box B checked with totals being carried to Schedule D (Form 1040), line 2.

Box C. Report on a Part I with box C checked all short-term transactions for which you can't check box A or B because you didn't receive a Form 1099-B (or substitute statement).

Code D. This code indicates a long-term transaction for which the cost or other basis is being reported to the IRS. Use this code to report a transaction that the recipient will report on Schedule D (Form 1040), line 8a, or on Form 8949 with box D checked with totals being carried to Schedule D (Form 1040), line 8b.

Code E. This code indicates a long-term transaction for which the cost or other basis is not being reported to the IRS. Use this code to report a transaction that the recipient will report on Form 8949 with box E checked, with totals being carried to Schedule D (Form 1040), line 9.

Box F.  Report on a Part II with box F checked all long-term transactions for which you can't check box D or E because you didn't receive a Form 1099-B (or substitute statement).

Code X. Use this code to report a transaction if you cannot determine whether the recipient should check box B or box E on Form 8949 because the holding period is unknown.
