You actually have a small loss that needs to be reported on the 2018 return.
Sale proceeds $188.95
Cost of stock $198.86
Loss $11 (rounded)
The reason it should be reported is first, it is income ($188.95) and 2nd the IRS gets the 1099DIV that shows this.
If you do not file an amended return, IRS would report the $188.95 for you and give you a $0 cost basis and then send you a bill for the taxes. They might not due to the small dollar amount but I would amend the return as no news from the IRS is good news.
It is not that difficult to Amend the return. --Also relax as millions file Amended returns each year. Your amended return will have no additional tax and possibly a dollar or two refund.
Once the return has been filed it cannot be stopped (unless you get extremely lucky and IRS would reject it for some reason).
So you have to wait for the return to be processed and you get your refund.
Then approx February 28th you can sign back into TurboTax and do the Amended return.
