Update a lookup field in CRM from Creator using deluge

Update a lookup field in CRM from Creator using deluge

I have a Creator form that creates a new account. When it creates the new account in the Accounts Module, I need it to also populate the Parent Account, which is a lookup field coming from the Module Parent Accounts, field Parent Account Name. I have tried numerous times to get this to work. I can get the New account to write but not the Parent account. Here is my code starting at the create new account. I will take any and all advice. Thank you!!
// Add NEW ACCOUNT
newAccountName = input.New_Account_Name1;
parentAccountId = "2073479000108966015"; // ID of the Parent Account

if (input.AccountsDD == "New Account") {
    newAccount = Map();
    newAccount.put("Account_Name", newAccountName);

    createResponse = zoho.crm.createRecord("Accounts", newAccount);

    if (createResponse.get("status") == "success") {
        newAccountId = createResponse.get("id");
        info "New account created successfully! ID: " + newAccountId;

        // Introduce a delay (optional)

        updateAccount = Map();
        updateAccount.put("Parent_Account_New", parentAccountId); // Use the correct API name and Parent Account ID

        response = zoho.crm.updateRecord("Accounts", newAccountId, updateAccount);

        info "Update Response: " + response; 
    }
}
