1099-DIV - Box 1a vs Box 1b. My 1099 only has Box 1b filled-in and TT doesn’t like that. What to do..?

You can call the issuer to verify that all dividenda are qualified. If so, enter the same amount in Box 1a. 

From 1099-DIV instructions.

Box 1a. Shows total ordinary dividends that are taxable. Include this amount on
the “Ordinary dividends” line of Form 1040 or 1040-SR. Also report it on
Schedule B (Form 1040), if required.
Box 1b. Shows the portion of the amount in box 1a that may be eligible for
reduced capital gains rates

To re-iterate the advice given by leeloo, you should contact the Form 1099-DIV issuer and request a corrected form.  

If there is anything shown in box 1b, that same amount or a larger amount should be shown in box 1a as well.  You cannot have qualified dividends without those also being considered ordinary dividends.
