PUB 721

I have retired this year 2020 from the FERS and Military.  Therefore, I am receiving an annuity from both.  I am also receiving monthly distributions from my TSP and South Carolina pays $100 monthly for retirees of the National Guard.   My wife is still working.  A few questions.  What is the best way to file, separate or joint?  Does your program/software support IRS Pub 721? I was told by HRO to use this publication while filing my first retirement year.   We have been using online Turbo Tax for over 10 years.
