How do I have to answer boxes 2b 3 6 8 9a if the boxes are empty on my 1099R form?

If those boxes are blank on your 1099-R, leave them blank in TurboTax. Not 0, but blank. These boxes are blank on most 1099-R forms. 

If you have boxes appearing in red and can't continue, try tabbing through them to clear the errors. 

If you need more help with this, please respond back with more details about what is happening when you complete this screen.

IF you are using "Online" turbotax

and 

IF you used that 1099-R form last year, and it transferred over to this year's software.

Then

Yes, you get a ridiculous page requiring entries in each and every $ box and each and every checkbox.'

(See below)

The easiest solution, is to:

1) scroll to the bottom of the page and click <Back>.

2) Then on the prior page, hit <Continue> 

...and this time, all the boxes will be available....but won't require an entry in every dang one...only the ones you need.

IF you don't do that, you get the pages below, where you are required to mess with EVERY box and checkbox:
