Form 5695

I installed a solar system in 2019 for $60783.  It is on a 5-year depreciation schedule.  I have $18,235 carry forward of tax credit.  I owe taxes this year so want to use it.  When I fill out form 5695, I only get $1,118 credit.  Either I entered something wrong, or I'm totally confused about being able th use the carryforward to decrease my tax liability. Thanks much.
