I'm having troubles with my school taxes it keeps saying I need to review them but I'm not sure what has happened

Do two things. First, look at your actual school form. Do you see an issue on the form? To print or view  your forms:

• In desktop, switch to Forms Mode. 
• For online:
  1. On the left side, select  Tax Tools
  2. Select Print center
  3. Select Print, save or preview this year's return
  4. If you have not paid, select pay now.

Second, look at the review error. Is it showing you the form with  a box highlighted or asking for additional information? Let us know what you are seeing and what the program is saying.

It keeps saying box 18 I reviewed several times and it’s not letting me put any information in the box. I have deleted and started over several times and I can’t figure it out. 

Boxes 18-20 should all be blank or all have entries.
