Are you actually getting and Error or just a Warning.

I file lots of returns with overrides (that dont affect the return, such as in the tax planner if I used that for some reason), or situations where I had a non-taxable disposition of a depreciable asset so I overrode depreciation.

I always get warnings, but never get an error that stops the return from being efiled.

If you know you want the override just ignore the warning and keep going.
