While that method used to work in prior years to stop the prompt, this year the choices made there had no effect (at least for me and some others.) Even after indicating "no" to all of the list in import options, all 1099's still kept asking to import. I think the manage option was broken when TurboTax developers changed the interface where 1099DIV/INT and investments are entered and probably didn't link it to the "manage import options".
