Your above comments don't show up, however I received 2 emails from TT with 2 further questions in them. I;ll try to answer them.
You say you did not receive any cash, but there is an entry in 1d of your 1099-b. did this amount go into your brokerage account? If so, then you still received it and need to report it. see below on how to amend your return based on which TT program you are using.
How do I amend a 2018 return in TurboTax online?
Amend your 2018 return if you need to change or correct something after you already filed it.
Keep in mind: You have 3 years from the date you filed your 2018 return (or 2 years after you paid the tax due, whichever is later) to file an amended return.
First, make sure you really need to amend and that your 2018 return was accepted in TurboTax Online or paper-filed through the mail. You can't amend a return that hasn't been filed yet.
Sign in to TurboTax and make sure you've selected Tax Home on the left side of your screen.
If you don't see this, select the menu icon in the upper-left corner to expand the menu.
Under Your tax return & documents, select 2018 and then Amend (change) return.
If you only see the option to amend 2017 or earlier, it's because you can't amend an unfiled 2018 return. Instead, just select Take me to my return, make your changes, and disregard the rest of these instructions.
Select Amend using TurboTax Online.
Carefully follow the instructions. Don't worry if your refund changes to $0. This is normal on amended returns.
When finished, we'll give you instructions for printing and mailing your amended return as amendments can't be e-filed.
Three weeks after mailing your amended return, you can start tracking it at the IRS Where's My Amended Return? tracking tool. Please allow at least 16 weeks for the IRS to process your amended return.
Processing times for amended state returns vary from state to state. If it's been more than 12 weeks since you mailed your amended state return, and you haven't heard anything, we suggest you contact your state tax agency.
To amend your 2018 return in the TurboTax CD/Download software:
Open the return you want to amend in your TurboTax software program.
Make sure your return is exactly as it was when you originally filed it.
If you made changes after you filed, undo them. We suggest comparing your on screen numbers with a paper copy of your filed return.
Now, make an "amend" copy your return by selecting Save As (Mac: select Duplicate) from the File menu. This preserves the originally-filed return.
Name the copy to distinguish it from the original, like 2018 Amended Smith B Form 1040 Return.
You should now be working inside the copy you'll be amending. Inside your program, search for amend and then click the Jump to link.
Select Continue on the We'll help you change (amend) your return screen.
On the following screen, Did you already file your return? select Yes, I've already filed my return and then select I need to amend my 2018 return. Select Continue and then carefully follow the instructions to amend.
Don't worry if your refund meter drops to 0; this is normal. Your calculations will come out correctly in the end.
When finished, we'll provide instructions for mailing your amended return, as amendments cannot be e-filed.
