"Turbotax should not allow a form to be added to your return unless the credit is allowed"
Perhaps it is a Turbo Tax issue. Form 2441 has always been in the federal return even when there was no dependent tax credit when there is a dependent care account. It is possible this requirement has changed with the tax law changes. If so, turbo tax is setting up the forms incorrectly. If not, the IRS is not set up correctly.
