I imported some already split fastq files to a qza file successfully.
qiime feature-table summarize command was successful too.
After exported the biom table, and converted to a text file. The OTU IDs are some thing like this

Nope! How did you create your feature table? If you used DADA2 or Deblur, those methods both hash the sequence as the feature ID by default:
--p-hashed-feature-ids / --p-no-hashed-feature-ids
If true, the feature ids in the resulting
table will be presented as hashes of the
sequences defining each feature. The hash
will always be the same for the same
sequence so this allows feature tables to be
merged across runs of this method. You
should only merge tables if the exact same
parameters are used for each run. [default:
True]
