ESPP stock sale basis cost data input

I had employee stock purchase plan sales when the company was bought out last year. I imported the 1099-B and I have the form 3922 for the fair market value at the date of the shares being exercised. I can find no way to enter the data in desktop turbotax product.  none of the fields are enterable, the help screen talks about a adjustment code on column f and adjustment amount in column g in form 8949but none of these fields allow entry of data - and what adjustment code would I use??
