Forgot to list my sister spouse in family section of i-130

[jnguy]

I filed online to petition for my sister’s family using form i-130. I listed her husband in the marriage info section but because of that in the family information (section 4) of the beneficiary which immediately follows, I only listed her kids as her family members thinking listing husband would be redundant. Do you think I need to call or mail to USCIS to correct this? It seems to be a difficult process to me. I am worried when they issue the approval, her husband is not included.

thank you.
