I am a full-time resident of New York. In 2019, part of my income came from and was taxed by California.
I've filled out all forms for both NY & CA in TurboTax, to the point that the NY section properly identifies the wage portion of the NY total that is already taxed by CA. The "Tax Computed on Your California Return" page reports the expected number, which is the amount of tax I paid to California.
However, the next screen ("Credit for Tax Paid to California") reports a lower tax credit to NY. I expected that it would exactly match the amount paid to CA. In this case, the difference is almost 50%.
What reasons could explain these numbers not matching up?
