If you rolled over from your company's 401(k) to your own IRA, you should not have received a 1099-B. Instead, you should have received a 1099-R and you would indicate this was a rollover which would not be a taxable transaction.
Generally speaking, you will not have a basis in any stock in your company's 401(k) that was rolled over to a traditional IRA. However, you do not pay taxes on this until you withdraw from your IRA. That would also be reported on a 1099-R, not a 1099-B.
If the retirement administrator of your company's 401(k) issued you a 1099-B, you may need to talk to them to sort out the source of the confusion. If this was employee stock not held in a 401(k), like stock in your company that you purchased at a discount, that would be treated differently and you would receive a 1099-B for that, even if you turned around and took the proceeds and contributed them to your IRA.
