<prompt> Human: My parents file my taxes along with their own, this includes my W2. I have another source of miscellaneous income that Id like to file without their knowledge. Would I be able to file that income separately with turbo tax?  <response>: Not very easily.I suppose you could file an amended return that they do not know about, after you file your return. When you sign your return, you are attesting that it is correct and complete. So there is that.A 1040X would require you to know some numbers from your original return, because you would be changing many of them.If your other income is self employment, youd need to include Schedule C and Schedule SE.
