Yes, you can and should file jointly as
it is the most beneficial filing status for married taxpayers. The fact that
you have very low income will help your husband's income (while file jointly) to be
reduced by 'joint' deductions, which may increase your refund/ lower your tax
liability.
As to which version you should use - If you are reporting self-employed income and expenses, our self-employed version handles that... you can always start with the lower versions, though. The program will ask to upgrade if it is necessary.
