Take a look at your 1040. Almost all additions to line 7 provide an acronym on the line 7 to define where its coming from.
The most common wage additions are:
-SCH scholarship income. This comes from the entry of your 1098-T and related info. That means your scholarship exceeds your tuition. This is by far the most common wages addition
-DCB dependent care benefit. $7000 is a bit much for this
-Moving expenses. This would occur when your W2 has an amount in Box 12 Code P and you haven't entered your moving information
-Excess 401k. You'd have a 1099R for this
