Sounds like this is another case of TurboTax's horrible delay problems entering data on certain screens.
The form to enter W-2 fields stalled on entry of each field value for me, to the tune of 5-10 seconds. This makes the program nearly unusable; I almost threw it out. A dozen or so people in forum discussions confirmed the exact problem I saw and a workaround emerged: Edit the form fields directly in the Forms view. This got me past the problem, but should not be necessary in a program of TurboTax's spread and maturity. "If it ain't broke, don't fix it!"
