Same thing happened to me!! I finally entered the Turbotax "forms" mode. So not the step by step mode. Look at your Turbotax software window and see the blue bar at the top. On the right hand side, there are 3 items at the top in the blue bar (forms or step by step, flags and notifications).
Click on the Forms icon. It will take you the forms mode.
Then in the left hand side there is a list of forms you have been using to fill in the data. Search for the K-1 and click on it, this will change your window and you will enter the window area for the K-1. Then you will scroll down and you should be able to manually enter the data you are trying to update. You want to make sure it all matches the lines on your K1 that you have from your accountant. Then make sure to save it. This should fix the problem.
