that's not the only broker not enter zero's
if they're type A or D (indicated on 1099-B) and assuming there are no wash sales, there's a summary section at the top of the 1099-B worksheet where you can just enter the total sales proceeds for all sales and the total cost for them - no details needed. there will be no 8949 since these flow directly to lines 1a or 8a of schedule D. . you can not import otherwise you will double up. so in TurboTax delete the import. if there are some with wash sales you can detail those while entering the totals for the others as indicated above.
