Turbo tax says we owe $2900!! My question is about filing married jointly vs. separately.?

I'm on SSD (~$18700, minus Medicare=$17,600, hubby made about $50,000) We took standard deduction as our itemized wasn't high enough. My question is: Since I don't get taxed on my SSD unless "our" income is over a certain amt, would we benefit from filing "married, filing separately"?, would that get around the taxes on my SSD because of hubbies income?--Yes, I could go through the whole process with Turbo tax, but I've been at this for over 8 hrs. just today--there were a few hours just gathering all the info, just to find out it's better to take standard deductions--ARGH!! (oh, sorry for that outburst--I think we all can relate) :) Thanks for any suggestions.
