In ProSeries we back the wages out as a negative on the Other Income line with the explanation "Excluded wages per IRS Notice 2014-7", I dont speak Lacerte, so Im not sure how you make that happen in your program.
Enter the wages as normal on Screen 10, wages. Then go to Screen 14.1, SS Benefits, Misc Income and look under Alimony and Other Income. There is a line to enter Medical waiver payments to care provider. Enter the wages there and they will be subtracted.
