If all of the state returns are for the same state, you already have the state program. You can use your desktop software for up to five federal returns and the corresponding state returns that go with them. It is an extra $25 fee to e-file a state return. You can avoid the state e-file fee if you print and mail the state. If you need to add the download for a second different state, it will cost about $45 for the second state program.
