Search/Label Soft 404 Crawl Errors- WordPress

Hi,

I have 15 soft 404 errors with crawl on both Yoast and therefore on Webtools. I think I know where they are from. Because they are Search/Labels that don’t exist on my blog. However, I migrated to WordPress.com from Blogger originally. I have since self hosted. I can only assume that some of the label data may have transferred from blogger , since they use label methods. The blog post that some of these labels are associated to, do not exist anymore and have since been deleted.

Does anyone know how I can get rid of these crawl errors because I have search the highs and lows of wordpress admin and go daddy hosting, and nothing contains these labels.

Thanks in advance.
