You can still file free if you make over $66,000 per year, it's just a more limited edition. I have used it for years with no problems. If you are comfortable with filling out the forms yourself and reading the accompanying IRS form instructions, you should be fine. It's federal only.
Protip: some of the forms do the math for you, but some don't. Also, there are no worksheets available. So, I use a spreadsheet to do the math and calculate the worksheets.
