My wife and I each filed Married Filing Separately federal and state returns in 2020. We decided that this was the wrong decision and I amended my return to Joint. My wife's Married Filing Separately was also amended once to return an overpayment.
The state of CA accepted the joint return and said nothing was owed, but assessed my wife $435.00 on her married filing separately return. Wasn't that return rendered null and void by the filing of our joint return. Why is she being assessed and how should I handle that assessment?
