I went back to 2022 and added this W2 as a test. The Forms View shows that a new section to W2 was added in 2023:
11 (cont) Sect. 457 and nonqualified plans State Allocation
For each row, enter state ID in col (a) and amount in col (b)
This is when the error comes up in 2023 that the amount in this 11 (cont) is not the same as in 11. Even when the amount is actually the same in my 2023 return.
