The TurboTax CD/Download software for 2017 will be available in mid to late November. TurboTax Online for 2017 will be available sometime in December. If you sign up for TurboTax Advantage you will be among the first to get the software when it is released. (When you sign up, make sure you are signing up for 2017, not 2018.)
But the IRS won't start accepting tax returns until sometime in January, and you can't file until you get all your W-2s, 1099s, etc. The issuers have until January 31 to send out those forms. If the father has consistently violated the court order, a better solution would probably be to talk to your lawyer about getting the court to enforce the order, rather than trying to race every year to file your tax return before the father does.
Are you the custodial parent? (Does your son live with you more than half the year?) If so, have you been claiming your son even though the father also claims him, or did you just give up? The IRS will not enforce the court order, but if you and the father both claim your son, the IRS will give the exemption to the custodial parent (unless the custodial parent has released the exemption to the noncustodial parent).
