All I could find on the support site was this reference to "boxes" my Turbotax programs do not have"
Enter the sales info and then click on the second box right below for
This sale involves an employee stock plan or an uncommon situation
Then click on Start Now.
Use the one sale at a time mode of entry. The small amount of dollars you're reporting on the attached picture means you just don't have very many trades to report and you might have thought that the "summary" entry method would be so much easier with understanding that you have to MAIL IN information after you file. Both Box 4 and Box 16 - the taxes boxes - are available to you if you enter one sale at a time.
Thank You! That might do it. I wonder why the program doesn't tell you that. In fact I initially did the long way, but all the 12 securities were bought and sold in the same year (2017) and the program wouldn't accept that so I went to Summary. I'll have to override, I guess and file a 1040X. Thanks again.
Since you took the Summary election, you won't get the option to enter a 1099-B tax withheld.
Instead list it as an "Estimated Tax Payment" under
Deductions and credits -- Other income taxes.
OR
go back and choose one sale at a time. You can't use Summary election for transactions with adjustments. (Withholding is not an adjustment.)
