Retirement tax questions

Another questions... When entering Gross Proceeds in Box A of 1099 B, TurboTax says number is too large for this field.  I checked TurboTax prior Q&A and one of answers was to split up proceeds into small sizes with number smaller than $8,999,999.  For example, if my proceeds and cost basis are $50,000,000 for 2015, I will need to split into 6 x $8,000,000 + $2,000,000 = $50,000,000.00.  Is that really ok?  

Thanks
