Amending a 2021 from Married Filing Separately to Married Filing Joint
The answer is hopefully as simple as it may seem or I'm missing a step.
In 2021 TT filed our returns as Married Filing Separately. I had started those 2 to see if we were better off filing separately rather than jointly. We weren't so I filled out a "joint" return that apparently was never filed. How do I make the change? Is it as simple as correcting one of the "separately" forms to "jointly"? And if so how do I file it as an amended return? Also does that mean 2022 will require an extension until 2021 is accepted?
Thanks in advance.
