My 1099-B is missing a date acquired and Cost Basis because it was bought in 1997. I researched and now know both the date and amount of $10,000.00. I left those boxes blank then chose : IF YOU HAVE ADDITIONAL INFORMATION ABOUT THIS SALE, you can enter it on your own. I did enter the date an cost basis. Did I do it correctly? I'm concerned because the $10,000 was not included in the 1099-B.
Essentially, I am wondering if TurboTax will use the Itemized sales which includes the $10,000 or the 1099-B which does not.
And, if I itemize Sales do I need to enter the 1099-B?
