I assume you mean, "Can you use TT Deluxe Online to file a 1040 including a schedule C or F or E, etc.?" Yes, you can, assuming your business is taxed on your 1040. However TT Home and Business provides additional help in filling out business-related forms. Some people filing business returns may prefer to work from a downloaded TT version on their computer, because of the additional complexity of the recordkeeping, but this is just a preference, not a requirement. The same is true regarding the different versions--Deluxe, Home & Business, etc. TT will generally steer you to the highest level product you can use, but as long as the forms you need are available in a lower level product, you can still use it to file your taxes, just with less hand-holding.
