I am using Turbotax Deluxe for 2018 and got the Form 2210 error that implied I under withheld. All the instructions to get around this error by deleting the form did not work. Here is what does work. When the error comes up in error check, go to the box with the "red x" that is checked in error and right click on that box. Choose override, delete the x and the form will go away.
