IRS Requiring Form 8283 for $500 on Schedule A line 12?

The IRS sent me a requirement for Form 8283 for my 2020 tax Return. I did claim $ 500 in Schedule A line 12 (Gifts to Charity other than Cash).   Instructions says you MUST attach Form 8283 if claim is OVER $ 500, so Turbo Tax did not generate it.
 
How do I generate it now, or should I answer the IRS that I didn't file it since I did claim only $ 500 and I don't need to file it?
 
Note: I have $ 10,436 Claimed on schedule A line 11 (Cash donations)
