MA State Tax. TurboTax coversheet says I'm owed a $7 refund after penalty/fees. My printed tax form says I'm getting $29. Error?

Massachusetts state tax question.

In April I couldn't finish my taxes so I did the extension and paid with the extension $628 to the state.  

Now I'm ready to file and see a discrepancy where the cover page says I'm owed $7 refund but my actual printed tax forms don't say $7 anywhere. In fact the tax form says $29 refund.  I don't want any problems with the Tax department, I'm happy to get $7, but why doesn't my tax form say $7?

Here is the info from my TurboTax cover page (filing instructions page):

After doing all the work of figuring out my taxes, my actual tax due was $599 but there was penalty/interest of $22, so the total tax due was $599 + $22 = $621 (it doesn't spell it out above but that's what I think, reading between the lines).

Remember I paid $628 in April with my extension, so the amount of the refund should be $7  ($628 - $621). The TurboTax cover sheet above says Refund with penalty is $7, I'm happy with that.

My problem is below, the actual tax form that's going to be sent out doesn't say $7. It says Refund $29. I don't want a problem with the state tax department... I don't want them to think I'm asking for $29, because I only want $7. Is this a bug and what should I do to fix this?

Thank you
