If you have the Online Premium version (not called Premiere) you can only do 1 return per account.
If you have the Desktop Premier version yes it can do multiple returns and efile 5 for free. Go up to File-New Tax Return. Then….This is important. If you do another return for someone else like your child and their name is the same or similar to yours then it might overwrite your return. You have to save each return with different names so you can tell them apart. Like if your name is John and your son is also named John it will save them with the same name so the second one will overwrite the first return. Go to File-SaveAs and give it a unique name.
