Because we do not have access to your 2017 and 2016 tax returns,
we are unable to tell you exactly why your refund increased, but we can offer
some possibilities
Try a
line by line comparison of your 2017 and 2016 returns-something
may jump out at you and prompt you to adjust your 2017 return.
To view
your 2017 Federal form 1040
1) Lower left side of the screen, click last category "Tax Tools"
.
2)
Select "Tools"
3) Select "View Tax Summary" under “Other Helpful Links”
4) Then back to the left-side of the screen, click "Preview 1040"
If a line by line
comparison does not reveal the difference, you should revisit all of your
entries for accuracy and completeness starting with your W-2(s). Look for
misplaced decimals or extra zeros
