On F1 (and the visa-dependent on F2) you are a nonresident alien for 5 calendar years and would need to file form 1040NR plus form 8843 as well as the dependent on F2, if they have no income, they would have to file form 8843.
Your filing status would be married filing separately.
Turbotax does not support this kind of return.
Have a look at Sprintax, or download the forms form the IRS website.
Also, have a look at publication 519: https://www.irs.gov/publications/p519/
