I knew about the limit when I called IRS to complain about not receiving my refund. They told me that they sent the refund by mail because the amount is more than $10k.


If there is no Official IRS limit on the amount of a tax refund that can be direct deposited then there is no way that TurboTax can tell you if the refund will be converted to a check by the IRS.  A comment by an IRS agent does not make that the official IRS policy.
