State tax filing

Thanks for the response, it’s helpful. The non resident states are not reciprocal. I have 3 besides resident state. The problem is that on the w2 from the employer all went to resident state instead of divided among the non-resident states. Do I need a corrected w2 from employer or in which screens of free file do I show what amount that went to each non-resident state? Do I do this in the income section at beginning or do I input the numbers exactly as they appear on the W2 and divide between states on each non-resident return afterward?

Thanks for your help
