In the tax and deductions worksheet is asking me to change the date on 1b(2). It currently has 01/01/2022, but it doesn't allow it. What date should I imput?

Did you move from one state to another during the year? If so, enter the first date you lived in your current state. 

When you enter the state abbreviation in column (1), the remainder of the row should automatically populate, except for the sales tax rate %.
