'TextChannel' object is not iterable | channel check not working

Question

Hi I'm trying to check to see if a channel already exists instead of creating a new one each time a member sends a modmail request. The error I get is

File "C:\Users\User\Desktop\Build 1.0.2\cogs\modmail.py", line 145, in on_message
if get(modmailchannel, name=f"{message.author.name.lower()}{message.author.discriminator}"):
File "C:\Users\User\AppData\Local\Programs\Python\Python37\lib\site-packages\discord\utils.py", line 271, in get
for elem in iterable:
TypeError: 'TextChannel' object is not iterable
enter code here

not sure why or the method is incorrect some how. The channel name that is created is the users name and discriminator. What I'm trying to achieve is if that channel already exists don't create another channel/post in the same channel.

Help appreicated

Here is the code I'm working with:

@commands.Cog.listener()

    if not isinstance(message.channel, discord.DMChannel) or message.author.id == self.bot.user.id:
        # not a DM, or it's just the bot itself
        return
    
    bucket = self._cd.get_bucket(message)
    retry_after = bucket.update_rate_limit()
    seconds = bucket.update_rate_limit()
    seconds = round(seconds, 2)
    hours, remainder = divmod(int(seconds), 3600)
    minutes, seconds = divmod(remainder, 60)
    if retry_after:
        pass
    else:

Instead of if get(modmailchannel, name=f"{message.author.name.lower()}{message.author.discriminator}"): use:

if modmailchannel.name == f"{message.author.name.lower()}{message.author.discriminator}":
