If your business is self employment or sole proprietor or a Single Member LLC it is a disregarded entity and you file it on Schedule C in your personal tax return. You can have a EIN for it.
If you have a Single Member LLC that is a S Corp you need to file a separate 1120S business return for it.
You can enter Schedule C Income into Online Deluxe or Premier but if you have any expenses you will have to upgrade to the Self Employed version or use any of the Desktop CD/Download programs.
