Difference Between TurboTax and Express NOA

Hello, I have just filed my 2023 taxes in Canada using TurboTax Online Self-Employed, according to TurboTax I had a balance owing of $5473.48. When I submitted my NetFile, within a few seconds I got the "Express Notice of Assessment" in which it says I have to pay taxes of $6198.46.  Within this Express Notice of Assessment, there is also a paragraph which says "We changed your total payable from $6,649.16 to $7,363.99 because of a calculation error."  All 4 of these numbers are different - $5473.48 (According to TurboTax), $6198.46 (According to top section of Express NOA),  $6,649.16 (mentioned in paragraph of Express NOA), and ($7,363.99 mentioned in paragraph of Express NOA as a change due to "calculation error").  Which one do I need to pay?  Why are these numbers different?  Why does TurboTax have a mistake and is different?  Thanks!
