Retirement tax questions

I just checked my refund status via IRS "Get Refund Status" web page and it shows that my refund was approved and the refund amount is what I expected.  Hopefully this is the case.  Supposed to be direct deposited in a few days.  I was very hesitant to e-file because of 4a<4b and because I had talked to an IRS agent who said 4a>4b and also because some people had issues with that and got over-refunded.  However others got the correct refund amount.
