Thank you for your confirmation and changes to the issue.
When I checked the source code in multiple versions, I found that the
description of TASK_HEAP_MEMORY in the
org.apache.flink.configuration.TaskManagerOptions class is also wrong. For
example, Flink 1.10. So in addition to the version you specified, do other
affected versions need to be repaired?
The source code and documentation need to fix. If possible, I can fix this
issue for the community.)

> Key: FLINK-22963
> URL: https://issues.apache.org/jira/browse/FLINK-22963
> Project: Flink
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 1.14.0, 1.13.1, 1.12.4
> Reporter: JasonLee
> Priority: Major
> Labels: documentation, starter
>
> When I studied the memory model of TaskManager, I found that there is a
> problem in the official document, which is the description of
> taskmanager.memory.task.heap.size is incorrect.
> According to the official memory model, I think the correct description
> should be that task Heap Memory size for TaskExecutors. This is the size of
> JVM heap memory reserved for tasks. If not specified, it will be derived as
> Total Flink Memory minus Framework Heap Memory, Framework Off-Heap Heap
> Memory, Task Off-Heap Memory, Managed Memory and Network Memory.
> However, in the official document, the Framework Off-Heap Heap Memory should
> be subtracted.
