The form that includes energy efficiency credits is broken right now. It may work ok for some people but does not work for all.
The credit for biomass stoves has been changed, for 2023 the credit is 30% of the cost for equipment plus installation with a maximum of $2000. It's on line 29a-29f of form 5695.
However, as mentioned, the credit can't be refunded unless you owe tax. If you already have enough credits or deductions to cancel any tax you owe, you can't get the credit. (This dos not mean a refund. For example, if your tax owed is $5000 and you had $6000 of withholding, you get a $1000 refund. That $5000 tax liability is the key number, not the refund amount.)
But in addition to that limit, the form is not working correctly for some taxpayers.
