Self employed

Thank you, that helped me get the numbers . 

 

Can You help with something else? 

When I uncheck married filing jointly to mf seperate, and spouse income and spouse is still listed under me, the turbotax program drops the tax amount by  roughly 32%. Why would that be since the combined income is still the same, adding spouses w-2 as mine . I would expect the tax to pay would raise.  I'd obviously like to pay less so is this just a glitch?

Thanks again
