Although the year-end value of the IRA is required to be present on Form 5498, it's misleading of TurboTax to only suggest that you can find the value there when preparing your tax return since you are likely preparing your tax return before the deadline for issuing Forms 5498. As an alternate source of this value, TurboTax should also be directing you to the year-end statement which the IRA custodian is required to provide for your IRA.
