Thank you so much for helping me out.
Also, your post about withholding is informative, thanks for sharing that. I understood that I could change my W-4 whenever needed and how to come up with an extra withholding amount. However, I wonder if there is a safer filing status to mention on my W-4 when I am not sure what filing status I will opt for the federal return next year. The primary aim is to avoid penalties for estimated tax underpayment.
