I've had this problem for years. Last time it took the tax expert hours to sort through it. Big flaw in the TurboTax form and no real direction since it was stated at the beginning of the process that no part was attributed to Oklahoma.
To fix it do the following: for each stock trade go to Edit. Check the box that says it is not subject to exclusion (this is terribly unclear becuase it is being excluded). You can continue and type in $0 for the oklahoma portion, but not sure if this is necessary. Just hit the Back arrow and the selection will be saved. No need to try to continue on to enter aquired dates and other nonsense.
This worked for me.
