UPDATED ANSWER
A small number of TurboTax Online users may be seeing their returns saying "In Progress" still in their TurboTax account after they have NetFiled.
If you successfully NetFiled, you should have received a NetFile Confirmation Number and your CRA My Account should say your return has "been received" or "assessed" by now.
