Capital Loss carry over from 2017 to 2018, did not show on my return. How can I claim it correctly?

In 2015 I had a short term capital loss of $10,000.00 and I deducted $3,000.00, and $7,000.00 was carried over to 2016, I deducted $3,000.00 in 2016 and $4,000.00 was carried over to 2017, I deducted $3,000.00 in 2017 and $1,000.00 was carried over to 2018 but the $1,000.00 did not show on my 2018 return while I was working on it. I completed 2018 return and did not get the amount correctly deducted. It show as Interest Loss. Confused in Carrollton, can you help?

The program I used cost & 79.99 is it Turbo Tax PLUS?
