Accessing TCGA Isoform Expression data

Question

[Jack]

Hello, I'm trying to do an analysis of cancer transcript expression preference from the harmonized database to check my own results and I'd like to use TCGA data. When I've worked with isoform expression before I've received it as a table with counts and ENST. I have used TCGAbiolinks before to download data from the TCGA. I feel like I'm just missing something right in front of me. If you have any advice I'd love to hear it!
