Section 179

Hello

 

I bought a sewing machine in 2017 for $18,000. I used Section 179 and took $6,000. (I may not be using the correct terminology). Can I use the remaining $12,000 on my taxes this year? I've never entirely understood Section 179 when a percentage or a specific amount is claimed.

 

Did the $12,000 just go poof and now it's not beneficial at all or how can I use it?

 

Thanks,
Lisa
