In their most recent update for tax professionals, Intuit indicated that the IRS would finalize for 8915-E on February 18. If true, then it should be in Turbotax within 1-2 weeks. However, The IRS also indicates that form 8915-E can't be e-filed.
Of course, The IRS could change or delay things at any time.
