To better document what occurred in my case.
I sold around $33K of betterment mutual fund as I closed out my betterment account.
When I imported my transactions from Betterment, TurboTax identified about 1,000 transactions were imported. Of those transactions 84 were labeled with an error. The instruction provided to go to the form in error and "remove" the $0.0 error and make it blank worked for 3 entries. The patterns that I saw were where the purchase and sale were rounded to $0.0 and the sale resulted in $0.0 entry. Other errors were exact sale values of $5 purchase and sale. I am using the downloaded version of Windows 10 of TurboTax premier. The instructions in that version of the software explain to go to the form, double click the field, use ctrl-d to override the value, clear the value. When you then click out of the field, the field stays in error even though it is now blank as per the instruction on the form. Note that by having these errors TurboTax will not allow online filing, it walks you through, in an infinite loop, the correction of the fields in the "reviews" mode which is entirely useless. Also, the editing of the slow and tedious with turbotax "calculating" between every modification. What I did was to remove the remaining 81 forms in error as the impact was a change of $2 in increased tax payment. CLEARLY TurboTax or Betterment has a problem on wash sales that result in a rounded value of $0.0. There is also another bug where editing the field to make it blank, by deleting the $0.0 value does not clear the TurboTax error. This occurred on sales ranging from $0.0 to $0.0 and on sales up to $13 and $14 that resulted in the less than .50 cents rounding issue. I would be more than happy to send TurboTax what ever information they need to troubleshoot because it was "hours" of fixing as even deleting the form was painful -- form deletes and then 30 second wait for turbotax to calculate, save the file, move on to the next form - try to edit the field, failure, delete form, 30 second wait to calculate, save file etc....
