I originally posted a related question regarding the fields being too small on the 1099-B Worksheet.  Because I have to report over $2B in sales, and the fields on the worksheet only allow 9 digits, I broke up the total and made 3 separate line entries.  The problem is even though the 9 digit entries are allowed, the totals (adding up to $2B +) cannot transfer properly to the appropriates lines on 8949 and Schedule D.  Those schedules only allowed 9 digits, so instead of $2B +, total was only showing at $999,999,999.  

I thought I could just override those total lines, but then the problem compounded to mess up AMT calculations.  At one point the tax bill doubled.  

As I see it, the only solution is to input whatever number in the 1099-B fields to force a net STCG total that matches the actual STCG; in this case, about $3M.  That way, the proper gain amount flows to other schedules.

I always attach a PDF of detailed support of every transaction adding up to the STCG.  The question is -- if the total sales and total basis don't match up between Schedule D and the detailed PDF, will that cause a problem.  Perhaps I could attach a statement explaining the field limitation issues, or would that further confuse the issue?

I have already discussed this with Intuit support, of course they have no fix for this.  

Any suggestions would be welcomed.
