Can a K3 be ignored if the K1 box 21 (foreign taxes) is blank?

I have received my K1, and for the first time, a K3. It seems that the K3 can be ignored if the K1 shows no foreign taxes being paid or accrued (K1, box 21 is blank).  So, can I just uncheck the K3 box in TurboTax and proceed with the K1? Thanks!
