I have done our taxes and my husband has refund and I owe. When I go to netfile, turbo tax indicates he has a refund of $84 and I owe $534, for a cumulative amount owing of $450. When I print our returns, they indicate he has a refund of $753, and I owe $1203, for a cumulative amount owing of $450. Why are the final balances different? Any suggestions?
