Smart Check error

Smart Check flagged 5 errors, all saying "Box 8 should have a value on the 1099-DIV" while the Brokerage form says "See Detail". TT shows "spaces" in the Imported 1099-DIV but not sure how I can choose "spaces" from the drop down in Box 8 in Scheduled B - Form 1099-DIV to get rid of the mismatch message. Thank you for the guidance!
