Antijen is run by Aunty - who hosts many lists relating to transitioning for both families and the person in transition. It's a great resource with very nice, understanding people behind it.
If your adjusted gross income is less than $56,000, you probably qualify to file online for free through the Free File program. Filing for both the state and federal returns are available for the program. The links above will let you know whether you qualify for the service, and, if you want, will recommend which companies you can use. Not all of them offer free state preparation or filing. You also get free e-filing, or you can choose to print your return and mail it.
More information on e-file is available on the IRS e-file website.
