You NEVER combine income or tax paid in different years on the same tax return. If you have more than one W-2 for the SAME tax year, you enter those W-2's one at a time in Federal>Wages & Income. After the first one, you click Add W-2 to enter the next one, until every W-2 for that tax year has been entered.
As for entering state tax paid---exactly what are you asking about? Do you mean you paid state tax due when you filed your previous year state return?
If you paid taxes due in 2019 to your state or local government, you can enter that by going to Federal> Deductions and Credits> Estimates and Other Taxes Paid> Other Income Taxes. You can enter the taxes you paid, but do not include any penalties or interest.
