A rollover from a 401(k) to a traditional IRA is considered under the law to be income, but nontaxable income. Entered properly, you should see the gross amount be included on Form 1040 line 4c but see the entire amount excluded from the taxable amount on line 4d. You should also see the word ROLLOVER next to line 4d.
By answering No to both questions asking if the rollover was to a type of Roth account you are telling TurboTax that the rollover reported on the code G Form 1099-R was to a traditional account. As long as the code G Form 1099-R does not have a nonzero amount in box 2a that would imply a rollover to a Roth account, you should see no effect of this rollover on your tax return other than inclusion on line 4c and the ROLLOVER notation.
