there is an option in Turbotax to remove imported data. you should be able to select just EPP. once done save the return reopen it and try again to import from EPP.
Note that with k-1 import, if you sold any that is not imported.
also K-3 info is not avaialble
finally, if you have an amount on 13K, Form 8990 is needed but that's not supported
