Why is this software not adjusting the unemployment to reduce by 10,200

If you have unemployment you can exclude up to 10,200 (for each spouse) if your income is under $150,000.  Your unemployment compensation will be on Schedule 1 line 7.  The exclusion will be on Schedule 1 Line 8 as a negative number. The result flows to Form 1040 Line 8.

For the Unemployment 10,200 exclusion......

Turbo Tax is updated for it.  You don't have to do anything special to get it.  It is automatic.  Just enter the full amount on your 1099G.  If the exclusion doesn't show up you may need to update the Desktop program. Go up to Online-Check for Updates,  for Mac close and open the program.  If updating doesn't fix it try doing a manual update for Windows

If updating doesn't help or you are using the Online version then delete the 1099G and re enter it.

The exclusion is reported on Schedule 1 Line 8 as a negative number.  The unemployment compensation received is on Line 7 of Schedule 1.  The result flows to Form 1040 Line 8.
