Making manual entries voids the accuracy guarantee, but still allows e-filing. What also blocks e-filing is making any manual overrides. I don't believe the IRC 1341 claim requires an override, but it does require a manual entry.
It occurs to me that since Turbotax has announced that Live help is available in all Online versions this year, that if you use the Live Online version, your accountant or CPA you are chatting with may be able to make the manual entry for you, and it might preserve the accuracy guarantee. I don't know this for sure, Live is a fairly new product and I don't know all the details of how it works. It is an extra cost add-on compared to the regular Online version.
