2023 AMENDED TAX RETURN - ADDING SCHEDULE C - CANNOT ADD EXPENSES

I am trying to amend my 2023 turbo tax return so that I can add a schedule C to it. I need to add the schedule C income AND expenses. I was able to add the self-employment business info and income, but the website keeps glitching and will not let me add the expenses for it. I have tried EVERYTHING!!! I cleared all history, cookies, caches, etc...... logged in and out.... tried different browsers, google chrome, microsoft edge, etc..... cleared history, cookies, cache again..... nothing!!! I am getting very very frustrated!! HOW TO ADD EXPENSES TO AN AMENDED RETURN WHEN ADDING A NEW SCHEDULE C BUSINESS??? My original 2023 return was just W-2 income, but I am trying to amend it to include self-employment schedule C income AND EXPENSES. It seems like the website is glitching because it has an "add expenses" button, and when I press it, it just reloads the same page and doesn't go to the add expense page. THIS IS SO ANNOYING!! I have read other post about people experiencing issues with amended returns adding schedule C expenses.... some have suggested that it is because I didn't buy the needed software for a schedule C when I originally filed and now there is no way to upgrade it for an amended tax return?? That does not seem right. I have to be able to amend my tax return. SOMEONE PLEASE HELP!!!!!!!!!
