1099-B

Hi,

 

I am working on my taxes and and one of my accounts could not be imported because it was closed in 2020.. On my 1099-B I under the Long Term Gains section I do have Box D checked with data that was send to the IRS (I guess it is the basis that was sent.....I really don't understand why just the basis was sent) and I do have Box E checked with data that was not reported. I also have another section that is titled "Unknown Term - Code X) and this has data in it that was apparently not reported to the IRS.

 

Shall I assume I need to enter the Box E and Code X data into Turbo Tax where I entered my sales info for the LT Gains that were reported? What does Turbo Tax mean when it says "Total adjustments to gains (losses) in this section. Do they want the realized gain or Loss? Do just combine the amounts from Box E and Code X? 

 

And I believe I need to send copies of the statements showing the exact things that were sold, am I correct? 

 

Thank you so much for your help.
