Enlisted military folks can prepare and file free if you add no extras, but you have added-on a feature that upgraded you to the most expensive of the TurboTax products--Live Self-Employed--by adding the Live feature, which allows for live on-demand help from a CPA/EA tax expert and a review of your return prior to filing.
You can remove that Live feature if you don't want it, then you'll be back in regular Self-Employed edition, which should be free for enlisted military. I assume you entered your military W-2 and answered the question about your rank, etc.
