If I turn off Mark Estimate, Override also goes away Line 14 Dist Inc K-1

I am the trustee for some small trusts.  The trust documents and my state law give me complete flexibility in allocating types of income between the single beneficiary of each trust and the trust to minimize taxes.  So I override the Turbotax calculation of the Amount Distributed to Beneficiaries on Line 14.  Turbotax automatically flags it as Estimated when I override.  If I turn the Estimated off, the Override goes away.
