some brokers report expired options in a way that TurboTax does not like.

This is a problem with the broker report, or with TurboTax, depending on your point of view.

If the broker hands you a negative number for proceeds or cost, I'd say it is the broker.

This is a confirmed TurboTax issue; when cents are entered, an adjustment form is generated. 

The developers are working on a fix.

Doubt the problem is with TDA, as I imagine my broker of ten plus years is reporting same way they have in past. Although I could be wrong in this and can check with them.

You are not wrong; the problem is with TurboTax and not your broker. 

If you want to test the foregoing assertion, all you have to do is round the numbers you are entering (i.e., do not enter cents). Some sort of programming error with rounding causes the adjustment worksheet to be generated and that is why the entries are being flagged.

Aside from rounding issue, there seems to be issues with negative numbers as well. The field is stating the minimum value is zero. So we should round to the nearest dollar to correct the problem and enter zero when it is negative?

I would suggest not doing anything until the developers resolve the primary issue.

"The developers are working on a fix". 

How can we know when the fix is implemented?  Is there a problem number that support can inquire on?  Or a signup list so that I can be notified when it is fixed? 

What do we do if it is not fixed by April 15?

[BTW, the screen this error appears on is unusable.  It has a very small scroll window for a very large number of lines on form 8949, and no clue as to the line on which the problem was detected.]

The nature of the bug is obvious:  Turbo tax sees a zero for cost basis and thinks it is a blank.  Zero is correct for a short put that expired worthless.
