After you file

i thought i started with turbo tax but i am mistaken, i used turbo tax the previous year.

i

did them with another company since i couldnt remember who i used after my computer went down, but have not mailed them yet. can i finish with or move them to with turbo tax so everything is in one place? suggestions would be helpful.

also if i am the caregiver of my fiancee and he is (was) totally disabled (he is now deceased) do i file him any different than just as a dependant at the time?
